Christie criticized his high school classmate for claiming that “evidence exists” that the governor knew about lane closures at the George Washington Bridge in September as they were happening.

“In David Wildstein’s past, people and newspaper accounts have described him as ‘tumultuous’ and someone who ‘made moves that were not productive,’ ” said a statement that, says Politico, was sent by Christie’s office to “friends and allies.’’

The statement trashes Wildstein — who got his $150,000-a-year Port Authority job through Christie and now is offering to rat out the governor in exchange for immunity from prosecution.

It even dredges up accusations dating back to their high school days, claiming Wildstein was “publicly accused by his . . . social studies teacher of deceptive behavior.”

More recent alleged transgressions, according to the statement, include Wildstein having a “strange habit of registering Web addresses for other people’s names without telling them” and writing as the “anonymous blogger known as Wally Edge.”

The statement also takes aim at The New York Times for its story quoting a letter to the PA from Wildstein’s lawyer, Alan Zegas, seeking reimbursment for his client’s legal bills.

“A media firestorm was set off by sloppy reporting from the New York Times and their suggestion that there was actually ‘evidence’ when it was a letter alleging that ‘evidence exists,’ ” the statement claimed.

“Forced to change the lead almost immediately, the Times was roundly criticized, and its editor was forced to issue this extraordinary statement to the Huffington Post: ‘We’ve made probably dozens of changes to the story to make it more precise. That was one of them. I bet there will be dozens more.’ ”

The Times responded Saturday night, saying, “We regularly update Web stories for clarity, as we did in this case. We do not note changes unless it involves an error.’’

Christie has been accused of orchestrating massive tieups on the bridge approaches to punish the mayor of Fort Lee for not endorsing him in the latest gubernatorial race.

Wildstein became infamous for his email exchange with Christie aide Bridget Anne Kelly, in which she wrote, “Time for some traffic problems in Fort Lee.”

He replied: “Got it.”

The special counsel for the state legislature’s Bridgegate probe, Reid J. Schar, said its investigation will continue despite a separate investigation being mounted by the US Attorney’s Office. “I am comfortable that the Committee’s investigation may continue,” he said.

“We will be mindful of the need to avoid taking steps that could inappropriately impede any investigation the US Attorney’s Office may be conducting.”

Earlier Saturday, Christie took to the stage in Times Square for a ceremonial Super Bowl handoff, then ran for daylight from Bridgegate questions.
